As the SPX3000 and the SPX4600 are both Sun Joe pressure washers, they benefit from the same level of quality and attention to detail.

Power Comparison

  • Fuel: Both units are electric pressure washers.
  • Engine & Pump: The Sun Joe SPX3000 and the Sun Joe SPX4600 both use an axial-type pump to put water under pressure. In either case, the pump is powered by a 14.5-amp motor.

The following charts are provided to show you at a glance how the main specs of the Sun Joe SPX3000 compare to the Sun Joe SPX4600.

  • Pressure: With a maximum reachable pressure of 3000 PSI, the Sun Joe SPX4600 provides a much higher force to blast off dirt and grime than the 2030 PSI of the Sun Joe SPX3000.
  • Water Flow: When operating at low pressure, the SPX3000 can generate a much higher maximum volume of water than the SPX4600. It can deliver up to 1.76 GPM (gallons per minute), whereas the SPX4600 offers a maximum water flow of 1.3 GPM. The former should thus allow you to rinse away dirt and debris with significantly better efficiency and speed.
  • Cleaning Power: With its 3900 C.U. (Cleaning Units = PSI x GPM), the SPX4600 offers a slightly higher overall cleaning efficiency than the Sun Joe SPX3000 and its 3572.8 C.U.

Design Comparison

  • Design: With its compact, portable design, the Sun Joe SPX3000 will be the better option if you consider portability, mobility, and ease of storage as important factors, as the Sun Joe SPX4600 can be considered less mobile, with a hand truck design.
  • Weight: Weighing 23.4 lbs, the SPX3000 is far lighter than the 36.6 lbs of the SPX4600.
  • Maneuverability: Both products benefit from a set of wheels, which greatly contributes to their maneuverability. The SPX3000 has a standard handle and the SPX4600 a foam-padded handle, both of which aid in maneuvering.

Feature Comparison

  • Soap Addition: Both washers allow for the addition of chemical detergent solutions to the water. For that, the SPX3000 has an advantage over the SPX4600. The latter offers a single soap tank, whereas the former benefits from a dual soap tank system that lets you easily store and use 2 different cleaning solutions.
  • Trigger Gun & Wand: Each of these 2 units comes with a fairly standard ergonomic trigger gun and a classic wand.
  • Nozzles: Out of the box, the SPX4600 and the SPX3000 both come with a 5-nozzle package. The set of included nozzles is the same in either case: 0°, 15°, 25°, 40°, and a soap nozzle.
  • Reach: Both products include a 20 ft high-pressure hose. Therefore, neither of them will, out of the box, allow for a higher freedom of movement around the unit. As both units feature a 35 ft power cord, their maximum allowable placement from an electrical outlet is the same.
  • Storage: The SPX3000 and SPX4600 both offer onboard storage that allows you to neatly keep the accessories you need at hand. Both washers feature a set of hooks to help you neatly store their high pressure hoses when not in use.
